12.4 If, under any law, whether as a result of a judgment against the Guarantor
or the liquidation of the Guarantor or for any other reason, any payment under
or in connection with this Guaranty is made or is recovered in a currency (the
"Other Currency") other than that in which it is required to be paid hereunder
(the "Original Currency") then, to the extent that the payment to the Lessor
(when converted at the rate of exchange on the date of payment or, in the case
of a liquidation, the latest date for the determination of liabilities permitted
by the applicable law) falls short of the amount unpaid under this Guaranty, the
Guarantor shall, as a separate and independent obligation, fully indemnify the
Lessor against the amount of the shortfall; and for the purposes of this
sub-clause, "rate of exchange" means the rate at which the Lessor is able on the
relevant date to purchase the original currency in New York with the other
currency.

12.5 Any determination and demand in respect of any amount at any time due and
owing by the Guarantor to the Lessor pursuant to this Guaranty shall be made on
the same basis as is applicable to a demand or determination made by the Lessor
under the Lease.
